Unable to download purchases because I changed my Apple ID
When I bought my new iPhone, I was unable to download purchased songs, because I had purchased them using a different Apple ID . So I had to put in my old Apple ID and password to download the songs. Now when I try and download new purchases , I get the message that I can't download for 75 days, because only one Apple ID can be us every 90 days.
iPhone 6s, iOS 9.3.5
